I was very anxious as early as possible to prove the structure as a unified self-supporting, mobile and easily handled flying corps as far as it had gone, and in June, 1914, this was done by the concentration in camp at Netheravon of the entire Military Wing, comprising Headquarters and Headquarters Flight, the four completed squadrons and the nucleus of No. 6 Squadron, the Aircraft Park and a detachment of the Kite Section. Mobilization, a very difficult process when it came, would have been almost impossible had the concentration not taken place. The object of the camp was a month's combined training to test personnel, both in the air and on the ground, and the handling of aircraft and transport both by day and night. Endeavours were made to solve by means of lectures, discussions and committees the problems connected with mobilization, technical and military training, observation, wireless telegraphy, signals, night flying, photography, bomb-dropping, workshops, stores, meteorology, transport, shifting of camp and aerodrome, supply and maintenance of units in the field, etc.--in fact the whole organization essential to the efficiency and cohesion of a Flying Corps, under conditions as similar as possible to those expected on active service. Very valuable experience was obtained from the work carried out. The necessarily wide gaps in our knowledge were brought home in more concrete form. It was also evident that the force was very small. But within three months it was proved under the strain of war that the organization and training had been laid down on sound principles. _The Naval Wing._ As in the case of the Army, it was to airships that the Navy first turned its attention, and the birth of naval aviation may be said to date from July 21st, 1908, when Admiral Bacon submitted proposals for the construction of a rigid airship, the ill-fated "Mayfly" which was destroyed on her preliminary trials. The Admiralty thereupon decided to discontinue the construction of airships, the development of which was left to the Army until May, 1914, when it was decided that all airships--that is No. 1 Squadron of the Military Wing--should be taken over by the Naval Wing. This was partly the result of a report by two Naval Officers, who visited France, Austria and Germany, as was the purchase of two vessels of the Parseval and Astra Torres types, and a small non-rigid from Willows. The construction of a number of other airships was ordered, but for various reasons was delayed or never completed up to the outbreak of war.
